Description

一种酒石酸阿利美嗪的口服液制备方法
技术领域
本发明属于药物制剂领域,涉及一种酒石酸阿利美嗪口服液及其制备方法,制剂制备工艺简单可控。
背景技术
酒石酸阿利美嗪是由罗纳普朗克公司于1958年开发的吩噻嗪类抗组胺药。其具有抗组胺作用,自主神经系统抑制作用,镇静作用,止痒作用,镇咳作用。能够治疗1)改善与皮肤病相关的痤疮(皮肤磨损,皮肤病,儿童期萎缩,中毒,咬伤)的症状。 2)改善荨麻疹的症状。 3)改善与上呼吸道炎症等相关的打喷嚏,流涕,咳嗽和过敏性鼻炎的症状。口服液体制剂与口服固体制剂相比具有较好的服药顺应性,对于吞咽有困难的儿童和老人而言,口服液体制剂显然更为方便,然后稳定性则是影响口服液体制剂大规模使用的重要因素;
目前尚未发现酒石酸阿利美嗪口服溶液的有关报道。
发明内容
本发明的目的在于提供一种稳定的酒石酸阿利美嗪口服溶液及其制备方法。本发明的酒石酸阿利美嗪口服溶液稳定性好,抗氧剂用了没食子酸丙酯,相比传统抗氧剂具有同等的抗氧化作用,且毒性更小,安全性更高。
实现上述目的的本发明的技术方案如下:本发明公开了一种酒石酸阿利美嗪口服液,该制剂由以下重量体积比的成分组成:0.05-1% 的酒石酸阿利美嗪、35-50%的溶剂、0.001-0.005%的抗氧剂、0.6-2.0%的pH缓冲剂、0.03-1%的矫味剂、0.001-0.5%的防腐剂。
所述的溶剂包括潜溶剂和纯化水。
所述的潜溶剂选自甘油、丙二醇中的一种或多种所述的抗氧剂为没食子酸丙酯。所述的pH缓冲剂为枸橼酸或其水合物、枸橼酸钠或其水合物。
所述的矫味剂为糖精钠和焦糖香精。
所述的防腐剂为羟苯乙酯。
上述酒石酸阿利美嗪口服溶液中,所述pH调节剂的用量为使口服溶液的pH值为2.5~3.85。
申请人经过大量试验发现:在该pH范围内,该阿利美嗪口服溶液具有较好的稳定性。
所述的酒石酸阿利美嗪口服液由以下步骤制备而成:(1)水相制备A、将缓冲剂、矫味剂溶解于适量纯化水中,得溶液1;B、将抗氧剂溶解于适量的纯化水中,得溶液2;C、将溶液1加入溶液2中,搅拌均匀,得溶液3;(2)有机相制备D、防腐剂溶解于潜溶剂中,得溶液4;(3)原料药的溶解 原料药溶解于适量纯化水中,得溶液5;(4)将溶液1、2、3、4、5混合均匀,静置除气泡,纯化水定容,即得。
具体实施方式
为了更好的理解本发明,下面通过对发明较佳具体实施例的描述,详细解释本发明,但不以任何形式限制本发明。
